Effect of nano- and micro- reinforced agents on dry sliding wear of polyester composites

Dry sliding wear of polyester hybrid composites containing carboxylic functionalized multi-walled carbon nanotubes (CNT) and microparticles, silica (SiO2) was studied at different sliding distances. An attempt has been made to produce uniform dispersion of nano- and micro- particles in the test samp...
